Sure. I've added 3 new hooks.
The first one is on:
/atum-multi-inventory/views/meta-boxes/product-data/inventory-group.php
It's located just before closing the div with the class name "inventory-fields":
do_action( 'atum/multi_inventory/after_inventory_fields', $inventory );
The second one is on:
/atum-multi-inventory/views/meta-boxes/order-items/inventory.php
It's located before closing the div with the class name "order-inventory-item":
do_action( 'atum/multi_inventory/after_order_item_inventory', $item, $inventory );
And the third one is on:
/atum-multi-inventory/views/meta-boxes/order-items/mi-panel.php
It's located before closing the div with the class name "order-item-mi-wrapper":
do_action( 'atum/multi_inventory/after_order_item_mi_panel', $item, $order_item_inventories );
Feel free to add any of them to your current version and use them as you wish, so when the next Multi-Inventory version is released, your customizations will continue working.
Best Regards,
Salva.
